I am thinking about putting a turbo kit on my 92 e36 325is. But I was wonder also interested in doing an engine swap to a M3. The problem I have is if I put a turbo kit on my 325, when I do the engine swap will it directly bolt on to the M3 engine? Please let me know.

Are you asking if your turbo kit you will put on the 325 fit on the M3 motor???... It might take a few adjustments... but ... each engine is relatively the same.. just a different size and computer software. So.. it should in theory fit.
